Contribution declined, again

I was entering the credits for tonight's episode of The Flash, All Doll'd Up. For some reason, the system declined the addition of Sterling Gates as a story editor.

This is fairly peculiar since I have added Sterling Gates to every episode of The Flash so far this season. Wouldn't the fact they he is credited as a story editor for the previous four episodes be fairly strong evidence that he is continuing to be a story editor for this series?
